BUNDREX steel fibers had been supplied in all kinds of shotcrete tunnels such as metro,
water, under sea line tunnel & mining all around the world.

Shotcrete

APPLICATION

Combining the best steel fiber technology with stable and affordable quality,
BUNDREX is widely used as a structural reinforcement for tunnel and precast

Ituango Hydro Power Plant (Colombia)

One of BUNDREX most important project in Colombia where 65/35CH steel fibers are being used.

AL MANDOUS PROJECT reinforced with 65/35CH steel fibers (U.A.E)

Reinforcing World Largest Oil Storage Tunnel

AL MANDOUS PROJECT reinforced with 65/35CH steel fibers (U.A.E)

It is big enough to store approx. 40 million barrels of oil thru tunnels in D-shape.

BUNDREX has experiences with all kinds of tunnel projects

Metro, High-speed train, hydro power, underground mining projects all over the world.

Advantages of BUNDREX®

    • Benefits

      - Increase reinforcement effects with wall of even thickness on a rugged surface
      - Increase tensile strength, bending strength, shear strength of concrete; no hollowing-out ; reduction of wall thickness(20%)
      - High resistance to cracking; increase in toughness (residual strength) after cracking Shotcrete construction possible right after excavation;
        drop in risk of cave-in disasters; rise in reinforcement effects and safety of permanent structures

    • Cost-effectiveness

      - Reduce labor costs, as no reinforcement assembly process is
         required Reduce working hours and construction costs

      - Reduce construction cost due to shortened construction period.

      - Reduce working hours and construction costs.

    • Quality

      - Streamlined work process; rise in quality and safety .

Precast

  • Features of BUNDREX®

  • Other Application for Shotcrete

Steel fiber reinforced sprayed concrete

Steel fiber reinforced sprayed concrete show better concrete performance and also safer and easier work, fibers are regarded as a better solution for reinforcement than mesh.
BUNDREX have supplied 450km long 500 tunnels (more than 200,000MT) with our steel fibers for sprayed concrete of NATM tunnels, which proves BUNDREX is the best solution for sprayed concrete.

Advantage of Steel fiber Reinforced Sprayed Concrete (vs. Mesh)

Shotcrete Construction Performance

• Experiences in all kinds of tunnel projects (Metro, High-speed train, Expressway / Hydro power, Underground & Electric line tunnel & Mining ]
• Overseas projects all around the world (Korea, Japan, Nepal, Taiwan / Canada, USA, Colombia, Peru, etc.)

Numerous number of construction
experiences, Provides optimum solution for
each construction site based on
professional work forcesand experience BUNDREX steel fibers had been supplied
in all kinds of shotcrete tunnels
such as metro, water, under sea line
tunnel & mining all around the world.
